Background and Purpose: Floating on water provides the opportunity for the elderly to exercise and take positions that may not be possible for them on the ground. The aim of this study was to explore the experiences of elderly women regarding barriers to hydrotherapy and how they can be ruled out.Methods: This qualitative study was performed using content analysis method in Guilan, north of Iran. A total of 23 elderly women undergoing hydrotherapy based on physician’s order were chosen through purposive sampling. Semi-structured interviews were conducted for data collection, which were analyzed using the method suggested by Graneheim and Lundman (2004). The study’s rigor was ensured and ethical considerations were considered during data collection and analysis.Results: Three main categories and nine subcategories, including internal barriers (lack of interest, insufficient knowledge, and doubt about its effectiveness), high expenses (expensive entrance fee, as well as expensive equipment and transportation), and environmental drawbacks (challenges of access, limited number of pools, and no companions), were developed during data analysis.Conclusion: Various factors were reported as barriers to hydrotherapy. The assessment of these barriers and resolving them can help improve quality of life in elderly women.
